QA/QC RAM analysis turret and mooring FPSO

jorgemartiresReliability, availability and maintainability analysis, Subsea engineering

MAR Consulting provided quality assurance (QA) and quality control (QC) of a Reliability, Availability and Maintainability (RAM) analysis of a turret and mooring of a Floating Production, Storage and Offloading (FPSO) vessel. The system consisted of a single point mooring and submerged turret production (STP), based on technology developed by the client. The RAM analysis documented the methodology and results in terms of production efficiency for the turret and mooring system.

HVAC system design review of FPSO lifetime extension

jorgemartiresFacilitation, HVAC, System design review

MAR Consulting facilitated a Design Review for the HVAC systems in a Floating Production, Storage and Offloading (FPSO) vessel, as part of lifetime extension modifications. The workshop was performed online with discipline experts from Engineering Contractors and Operator. The workshop was structured as a qualitative analysis following a list of guidewords to make use of the multidisciplinary experience and knowledge of the participants. The objectives of the workshop were to: Identify gaps towards Authorities rules & regulations and Client / project requirements; Review the current design with regards to safety, operability, and maintainability, i.e., areas where it may represent a […]

QA of RAM analysis for FPSO stationed in Norway

jorgemartiresReliability, availability and maintainability analysis

MAR Consulting AS had assisted on producing a reliability, availability, and maintainability (RAM) analysis of a floating production storage and offloading (FPSO) unit to be stationed in the Norwegian continental shelf (see the previous article here). The initial model in the front-end engineering (FEED) phase had the objective of estimating the production efficiency of the current configuration, providing insight on bad actors and basis for modifications to improve the production efficiency. Since then, the model was further developed to include further details during the design and detailed engineering phase. The objective is to provide a more accurate estimate of the […]

Cyber-security assessment of FPSO IT/OT systems

jorgemartiresCybersecurity

MAR Consulting performed a cyber-security assessment of a floating, production, storage and offloading (FPSO) vessel operating in the Norwegian Continental Shelf (NCS). The methodology used was similar to previous studies delivered by MAR Consulting. Please refer to (1, 2, 3, 4) for further details on the methodology or feel free to contact us. There were a number of key findings. Specifically, regarding interfaces between different systems; culture and awareness surrounding cyber-security; and potential backdoors to some IT/OT systems in the vessel. It was shown that the most critical control and automation process equipment were protected with several layers. Inherent safety […]

FPSO availability effect on 3rd party liquid evacuation

jorgemartiresReliability, availability and maintainability analysis

MAR Consulting performed an availability study of a floating, production, storage and offloading (FPSO), which will be operating in the Eastern Mediterranean Sea. The development plan envisages the use of an FPSO with full offshore processing capabilities of the reservoir fluids. Conditioned gas will be exported to shore and tie-in to the country’s gas distribution grid. The associated light oil will be exported offshore by tandem offloading to a shuttle tank. The FPSO storage tanks were being considered to evacuate a third-party operator light oil from a nearby field, in addition to the light oil from the FPSO’s own operating field. […]

SIL study of over-speed modules for gas turbine generators and compressors

jorgemartiresFunctional safety, Safety and reliability engineering

MAR Consulting performed a functional safety/SIL study of over-speed safety instrumented functions (SIF) protecting gas turbine generators (GTG) and gas compressors installed in a floating, production, storage and offloading (FPSO) vessel. The SIFs included 2oo3 voting speed sensors and 1oo3 voting valves controlled by over-speed modules. The work covered the following phases of the safety instrumented system (SIS) lifecycle, as per IEC61511 Ed.1 and the client’s internal guidelines: Allocation of functions to protection layers (phase 2) using layers of protection analysis (LOPA); Safety requirements specification (SRS) (phase 3) with general and specific one-pagers SRS datasheets; Safety integrity level (SIL) compliance (phase […]
